This one is more of a netiquette question.
Sometimes I stumble on "unanswered" questions that were actually answered - in their comments.
Those questions are shown as unanswered in the statistics.
For example: http://stackoverflow.com/questions/4719699/composite-javascripts-in-c-asp-net-with-the-aspscriptmanager.
What should be done?
Flag the question so one moderator can somehow mark it as answered.
Answer the question yourself (as a community wiki answer), mostly by copying the comments.
Nothing. Move along.
EDIT
I'm talking about questions without activity for weeks or months.
Feature request
Give diamond-mods the ability to change a comment to an answer; and allow users to flag for this action.
